The goals of vitrectomy are to clear the media, to relieve traction, to reattach the retina, to remove tissue or foreign material or to obtain a vitreous biopsy. According to the vitreoretinal pathology the surgeon can combine certain steps and algorithms to achieve these objectives.

A simple vitreous haemorrhage or a case of endophthalmitis is managed by core vitrectomy. The central vitreous is removed to clear the vitreous cavity from axial opacities.

Epiretinal Surgery is undertaken to remove vascularized, tightly adherent or non-vascularised membranes from the retinal surface. Peeling, segmentation and delamination are the three main methods of removal of an epiretinal membrane, depending on the type of membrane. Non-vascularized membranes (e.g Macular Pucker) are loosely attached to the underlying retina and can be peeled off with minimal trauma. Segmentation of vascularized membranes is done with vertical scissors to relieve tangential traction and reduce the membrane to a number of separate segments. Removal of an ERM can be achieved by delaminating it as a single sheet with horizontal scissors.

In cases of anterior loop formation (following previous vitrectomy or as a feature of PVR, ROP or trauma) special attention has to be paid to vitreous base surgery. Anterior loops can usually be relieved by membrane sectioning techniques. The anterior peripheral vitreous is removed with the vitreous cutter, using scleral depression and co- axial illumination. To achieve adequate peripheral dissection it is necessary to remove the lens including the posterior capsule. If traction remains after extensive membrane dissection a peripheral retinotomy might be required. A high broad encircling scleral buckle is used to support the vitreous base and release peripheral traction. Silicone oil is used as a long-term endotamponade to stabilise the retina.

Advances in vitreoretinal techniques allow subretinal surgery to approach a variety of clinical problems such as choroidal neovascular membranes (CNV) and thick subretinal haemorrhages. Following a standard three-port vitrectomy and induction of a posterior vitreous detachment a small retinotomy is made temporally to the macula. A small amount of BSS is injected subretinally to create working space. The membrane is freed and removed with a subretinal forceps while the IOP is raised to 80 mmttg to avoid haemorrhage. In the same way subretinal blood clots can be removed mechanically. However, if the haemorrhage is not older than 5-7 days extraction can be facilitated by a subretinal injection of t-PA.

With the ageing process, inflammations, PVR and vascular diseases there is a tendency to form epiretinal membranes. These membranes by their thickness, puckering,oedema, bleedind etc reduce the vision whenever involving the macular region. Trans Parsplana surgery for these membrane is a boon and achieves sucess rates of over 955. As with any other Surgery the surgeons have lots of tricks of personalised nature to tackle these membrane.

THE PREVALENCE OF AGE-RELATED MACULOPATHY IN SOUTH INDIA

(V. Narendran, R.D. Thulasiraj, Kim, Selvaraj, J. Katz, A.R. Robin, J.M. Tielsch)

Aravind Eye Hospitals, Tamilnadu, India; Johns Hopkins University, Baltimore, MD.

 

 

Purpose: To estimate the prevalence and severity of age-related maculopathy (ARM) in a rural south Indian population.

 

Methods: A cluster sampling approach in 2 districts of Tamilnadu state in south India identified 17, 200 persons of whom 5539 were 40 or older. All subjects received a screening exam in the village and, for those 40 or older. a comprehensive exam at the Aravind Eye Hospital. Participants also received an interview on medical history and basic laboratory measurements. ARM was defined according to the international classification during a dilated fundus exam at the slit lamp and with indirect.

 

Results :5150 persons received examination, of whom 4939 had complete data on the interview and retinal exam. The prevalence of large, soft dursen increased from 0.7% among those 40-49 to 2.6% among those in their 50s and 60s, to 4.5% among persons 70 or older. There were only 6 cases of exudative AMD, all among persons 60 or older. The prevalence of geographic atrophy increased from 5/10,000 among persons in their 40s to 1.1% among those 70 or older. There was no difference in prevalence between men and women in this population.

 

Conclusions: The prevalence of large, soft drusen and late AMD rose significantly with increased age to almost 1 in 20 persons 70 years old or older. This prevalence is similar to the age-specific prevalence figures found among white populations in the West and suggests that the low prevalence found among blacks in the West has little to do with pigmentation as south Indians are also heavily pigmented.

 

CATARACT SURGERY AND DIABETIC RETINOPATHY

Education & Research, Chandigarh 160 012

 

Patients with diabetic mellitus have an increased risk of developing cataract. Many such patients have preexisting diabetic retinopathy at the time of cataract surgery. While, more than 90% of the patients who have no preexisting diabetic retinopathy carry a good visual prognosis and eventually have 20/40 or better visual acuity, nearly one-third of patients with preexisting retinopathy may show retinopathy progression. Postoperative angiographic macular edema is more common in diabetics but resolves spontaneously in patients with no or minimal diabetic retinopathy. In patients with moderately severe NDDR or more, clinically significant macular edema tends to persist, may arise de-novo or even worsen after cataract surgery. Diabetic patients ned a preoperative characterisation of their retinopathy and a thorough discussion with the patients about the need for cataract surgery at the risk of progression of retinopathy is motivated. Currently early surgery is favoured before development of significant retinopathy rather than wait for cataract to become more dense. All efforts shall be made to stabilise diabetic retinopathy with appropriate laser treatment before cataract surgery. All diabetic patients need close observation for at least six months following surgery to intervene with laser photocoagulation as and when to prevent visual loss from diabetic maculopathy and other consequences of diabetic retinopathy.

 

 

CYSTOID MACULAR EDEMA

Cystoid Macular Edema(CME) is characteristic, often self-limitingmanifestation of a wide variety of ocular disorders, and can occur following uncomplicated or complicated conventional cataract surgery or phacoemulsification, with or without intraocular lens implantation. CME may be the reason for reduced vision several weeks or months after surgery, or may be the reason for impaired vision soon after surgery. Visual acuity may remain normal but contrast sensitivity could be affected. The real incidence of CME is difficult to ascertain, and will depend on methods used to identify CME, the surgical techniques employed , the period during which CME is sought, and whether or not visual acuity is taken into account. The overall incidence is low, and tends to increase after intracapsular extraction, primary posterior capsulotomies, accidental rents in the posterior capsule, and after planned ND Yag capsulotomies. Surgical trauma that implicates prostaglandins, a disorganised anterior segment, associated uveal inflammation, and break down of the ocular barriers are thought to be responsible for the development of CME. One of the theories suggest a primary dysfunction of the Mueller’s cells while others suggest that fluid collects within the inner plexiform and inner layers of the retina. The oedema is evident by most methods of fundus examination, fluorescein angiography, and optical coherence tomography. Management consists of surgical restoration of the anterior segment if it is distorted, the use of steroids when there is associated inflammation, and the use of one or more of the several drugs through different routes that are believed to resolve established CME or prevent its occurrence. Oral acetazolamide 250mg. a day for two weeks repeated if necessary, resolves the oedema and improves vision in many patients, and should be recommended, provided they are tolerant to its side-effects.

DROPPED LENS AND IOL

Modern pars plana vitrectomy as well as the availability of PFCLs has revolutionized the management of dropped nuclei / IOLs with excellent visual outcome.

With adequate patience and perseverence (essential for a vitreoretinal surgeon) even 3+ to 4+ nuclei can be removed through the pars plana approach by alternating crushing between instruments and suction (Cutter with high suction and low cutting rate) without the need of an ultrasonic fragmatome or a limbal incision.

Dislocated IOLs can however be floated up on a cushion of PFCL and removed,exchanged (ant.cham.IOL,iris claw IOL,scleral fixated IOL) or repositioned provided there is adequate capsular support.

  1. Scleral buckling with or without exansile gases a study of fifty cases. Ranjan Chowdhary,- Calcutta.

    2. Expansile intra-ocular gases like SF6 and C3F8 has added a new dimension to the treatment of retinal detachment. In our study between August’ 98 and July, 2000, we operated upon 50 patients of RD. The same surgeon buckled all the patients. Of these 31 patients were injected with expansile gases and the rest 19 treated along traditional lines. In this exposition we discuss the method of injection the gases and the comparative results of the two groups and have come to the conclusion that expansile gases may give a better statistical possibility for re-attachment of the retina.

  2. Scleral buckling for stages 4 and 5 retinopathy of prematurity. Pramod Bhende, Kaushal B Bhavsar, Lingam Gopal, Nitin B Shetty, -Chennai.

    3. To analyze results of 360 degree encirclage in eyes with stage 4 and 5 ROP. We retrospectively reviewed 12 eyes ( 10 infants) that had encirclage with 240 band. 10 of the 12 eyes had stage 4 and 2 had stage 5ROP. 3 eyes had prior laser and 1 had cryotherapy. Cutting /band removal was done in 5 eyes at mean of 32 weeks. At mean follow up of 48.92 weeks, 10 eyes had attached retina, one underwent parsplana vitrectomy and one developed severe hypotony. Scleral buckling is an effective procedure in stage 4 and selected stage 5 ROP eyes.

  3. Risk factors for threshold retinopathy of prematurity. Anuradha Sharma, M.R.Dogra, Subina Narang, Saurav Dutta, Anuradha Sharma, Amod Gupta, -Chandigarh.

    4. There is little information available on the risk factors leading to progression of Retinopathy of prematurity (ROP) to threshold ROP. The purpose of the study was to determine independent risk factors in the development of threshold ROP in our set up. We retrospectively reviewed neonatal records of 108 premature infants with retinopathy of prematurity who were born were under the neonatal services of our institute between 1995 to 1999. The study group comprised of 55 babies with threshold ROP which was compared with control group comprising of 53 babies with subthreshold retinopathy of prematurity. Both the groups were matched for age and birth weight. Total of twenty seven antenatal and neonatal risk factors were analysed. Multivariate analysis using stepwise logistic forward regression showed that anaemia and double volume exchange transfusion (p<0.02) were the only independent risk factors in the development of threshold ROP.

     

  4. Efficacy of various laser wavelengths in the treatment of diabetic macular edema. Vishali Gupta, Amod Gupta, Ravinder Kaur, Subina Narang, M.R.Dogra,-Chandigarh.

    5. There is little data on the efficacy of Nd. Yag laser compared to other well established laser wavelengths in the management of diabetic macular edema. 271 eyes of 164 diabetic patients with clinically significant macular edema (CSME) were sequentially lasered with four different wavelengths. Follow up was conducted for a min. of months ( 9.8 + 1.3 mos) Reduction/ elimination of CSME was observed in 56/60 (93.3%) of eyes treated with argon green (514 nm); 54/61 (88.5%) with krypton red (647 nm); 66/71 with frequency doubled Nd Yag (532 nm) and 67/79 with diode (810nm) laser. The number of eyes requiring re-treatments was highest (44.3%) with diode and least ( 15.5%) with frequency doubled Nd Yag (P= 0.0002).

     

  5. Role of prophylactic intravitreal antibiotics in open Globe injury. Amod Gupta, Vishali Gupta, Subina Narang, Sayan Das. -Chandigarh.

    6. There are no difinitive guidelines to prevent post traumatic endophthalmitis which remains a major clinical challenge after open globe injury. We carried out a prospective randomized controlled trial of 68 patients of open globe injury seen between January, 1999 to January, 2000. All the patients were non-infected at presentation. Group-1 patients (33) received intravitreal vancomycin (1mg) and ceftazidime(2.25mg) at the time of primary repair while group-II (35) did not receive any intravitreal antibiotics. Both groups received intravenous ciprofloxacillin/ Ofloxacillin (200 mg BD) for five days. Of the 33 patients in group 1, only two (6%) developed endopthalmitis after three weeks of injury and both had cilia in the vitreous cavity detected at the time of vitrectomy. Of the 35 patients in group II, 4 (12%) developed endophthalmitis. Thus prophylactic intravitreal antibiotics helped in lowering the incidence of post traumatic endophthalmitis.

     

  6. Visual outcome after successful diabetic vitrectomy. B Maheswar, V R Saravanan, V Raghuraman, N Sunil V Narendran, -Coimbatore.

    7. Vitrectomy is performed in Diabetic retinopathy for various reasons including non-resolving vitreous haemorrhage, traction retinal detachments threatening macula etc. However the visual outcome may not be good even after successful vitrectomy. We analysed the cause of variable visual outcomes in 50 successful cases of diabetic vitretomy. Causes of poor visual outcome included optic disc pallor, macular ischaemia, long standing macular TRD, severe CSME etc. The results of the study shall be presented.

  7. Redetachments after silicone oil removal-causes and anagement. Raghuraman, V R Saravanan, B Maheswar, N Sunil, V Narendran, -Coimbatore.

    8. Silicone oil is commonly used as long term tamponading agent in various vitreo retinal surgeries. Removal is usually performed 4 to 6 months after surgery. We present 10 cases ( 6 RD, 2 GRT, 1 Vasculitis, 1 Coloboma with RD) in which silicone oil removal was followed by redetachment. The causes were reopening of old breaks (5 cases), fomation of new breaks (2 cases), proliferation of membranes (case of vasculitis) and unknown cause in 2. Resurgery was performed with successful reattachment in all the cases. The visual outcome and complications are discussed.

  8. Juvenile X-linked retinoschisis (JXLR) clinical Panorama and Management Dilemmas. Shukla D, P S Aruna, P Namperumalsamy, -Madurai.

    9. We retrospectively analysed 15 cases of this rare vitreoretinal dystrophy. All were young (10-34 yrs) males with congenitally poor vision (6/12p-PL). 12 had pathognomonic foveal schisis; 3 had post- schisis macular degeneration-2 with nasally dragged posterior pole. Other features included temporal schisis, vitreous veils etc., ERG demonstrated typical wave suppression (b>a); FFA ruled out cystoid macular edema. 4 peripheral schises were laser- barraged, 3 developed RD; one settled with buckling, 2( post-barrage) needed vitrectomy also. One case redetached, 3 had spontaneously reattached RD. Prophylactic photocoagulation may be of doubtful value. Regular follow up is essential for early management of sequelae/ complications of this progressive disease.

     

  9. Ultrasound in the diagnosis and management Of Posterior scleritis. Hemanth Murthy, N S Muralidhar –Bangalore.

    10. To study the varied presentations of posterior scleritis and to highlight the role of B-Scan ultrasound in the diagnosis and management of posterior scleritis, 11 patients were studied in the period 1996 – 2000. The various clinical presentations were studied and the diagnosis was confirmed on ultrasound. These patients were then started on systemic steroids/ immunosupressive treatment. The response to treatment was observed on B-

    Scan and the treatment titrated accordingly. We observed that posterior scleritis is frequently missed due to varied presentations and the B-Scan provided an excellent diagnostic and follow up tool in these cases.

  10. Threshold retinopathy of prematurity in infants With birth weight more than 1200 gms. Narang Subina, M R Dogra, Anuradha , Amod Gupta, Anil Narang –Chandigarh.

    11. Retinopathy of prematurity ( ROP) is well described in babies with birth weigth less than 1200 grams and many studies recommend ROP screening of premature babies <1200 grams. We retrospectively evaluated 42 eyes of threshold ROP in 22 premature babies with birth weight more than 1250 grams. The mean birth weight was 1433 grams and the mean period of gestation was 29.33 weeks. 38 eyes were subjected to cryotherapy or laser treatment. Of the 4 eyes that could not be subjected to treatment on the initial visit, 2 eyes showed spontaneous regression and 2 eyes progressed to 4 disease. Of the treated eyes ROP resolved in 35 eyes and 3 eyes progressed to stage 4-5 disease. The sequelae of ROP included macular drag (11 eyes) disc drag(14 eyes)and vessel tortousity (5 eyes). Threshold ROP requiring treatment is seen in premature infants with birthweight more than 1250 gms and thus these babies should also be screened.

  11. Transpulillary thermotherapy as a modality of treatment for subfoveal neovascular membranes. Manish Nagpal, Shobhana Sharma -Ahmedabad.

    12. To study the role of transpupillary Thermotherapy (TTT) in stabilization and regression of subfoveal membranes, 32 consecutive patients of subfoveal membranes were treated with TTT using a 810 nm laser with a large spot size Power setting needed to be titrated for the pigmented eyes since the western parameters were found to be too high for asian eyes. 30% of the patients improved in visual acuity, 40% stabilized and 10% deteriorated following the treatment. TTT is new modality of treatment for subfoveal meambranes and it needs to be further evaluated with a longer follow up to define its actual role.

  12. Clinico-microbiological profile and treatment outcome of endophthalmitis in a paediatric population- A retrospective study. Vasumathy Vedhamtham, Nazimul Hussain -Hyderabad.

Out of the 62 cases of paediatric endophthalmitis that were analyzes trauma was the commonest aetiology (49 cases, 79.03%), 11 cases were due to a presumed endogenous cause. Microbiological work up was positive in 31 cases (50.82 %), with polymicrobial infections, being the commonest (11 cases, 35.48%). Of all the possible variables analysed, only the type of surgical intervention was found to be a statistically significant factor to have a bearing on the visual outcome, with the use of vitrectomy being associated with a better outcome in selected cases.

    5. Parsplana Vitrectomy with the help of Erbium- Yag Laser was done in 26 eyes. The pathologies varied from simple vitreous haemorrhage to Retinal detachment with PVR. Erbium –Yag laser has the highest water absorption, so that there is minimal damage to the tissues.

  5. Indocynanine assited ILM removal. Indu singh - Amritsar.

    6. To increase the success rate of macular hole surgery, it is now imperative to peal internal limiting membrane, also known as maculorhexis. We have used ICG dye intraviterally to stain ILM so that this can be peeled easily. Even in the cases of retinal detachment with PVR, Advanced diabetic retinaopathy, Proliferative Eales, to avoid macular pucker post operatively, ILM removal can be done easily by staining with ICG.

The tear is then located on the sclera and 287 tire placed as explant to support the tear and the vitreous base. Adequate laser retinopexy is performed & the PFCL is exchanged for silicon oil.

  7. Importance of vitreous base surgery in vitro retinal cases. Nabin

    8. Patnaik - New Delhi.

    Complete removal of vitreous base has been advocated by Dr. R. Zivojnovic and later on by Carl Claes from Europe. The vitreous base can be a potential enemy in posterior segment surgery. The importance of removal of vitreous base and reduction of recurrence of retinal detachment in number of vitreo-retinal cases will be highlighted. The vitreos base removal technique by diamond dusted scleral depressor and advancement of new tool will be presented.

  8. Nucleus drop in management our experience. Mohan Rajan, Sujatha Mohan - Chennai.

    9. 39 eyes which underwent phacoemulsification and had nucleus drop into the vitreous cavity between, January 1996 and April 2000 were analysed. The nucleus drop varied from whole nucleus drop to less than a quarter in these eyes. All the eyes underwent phacoemulsification through 3mm clear corneal temporal incision. The incidence of nucleus drop, management of the same and the post operative results and complications are being analysed. The visual acuity at the end of 3 years follow up was 6/12 or better in 30 eyes, 6/60 – 6/18 in six eyes and less than 6/60 in 3 eyes. The various techniques we have employed to retrieve the nucleus has been found to be safe.

    10. A new directional endolaser probe can be moved in any direction and cab be lenghened/ shortened inside the eye serves very useful to do laser particularly in periphry. The second instrument is a retinal –knife – light – probe proves very useful in dissecting membranes and gives additional freedom of doing bi-manual surgery. Third a soft tipped aspirating –canula- cautery serves dual function of cauterization and aspiration of blood. Fourth irrigating microretinal- pick is useful for dissecting membranes.

  10. Vitrectomy a treatment modality of subretinal cysticircosis. Harsha Bhattacharjee- Beltola.

    11. Exudative retinal detachment severe uveitis and blindness are the common presentation of ocular cysticircosis. A case of subretinal cysticircosis was treated by PPV, Belt buckling, Retinotomy, MP, removal of cysticirca cyst through pars plana route, FGE, Endo laser and Silicon Oil. Silicon Oil was removed and subsequently phacoemulsification of cataract and foldable lens was implanted. Final visual acuity was 6/18 in this eye after one year.

  11. Ultrasound biomicroscopy in silicone oil filled eyes. Li Wenhua, Taraprasad Das, Subhadra Jalali - Hyderabad.

    12. To evaluate intraocular silicone oil image pattern, distribution and anatomic relationship of silicone oil in the eye ultrasound biomicroscopy was done. 23 eyes underwent vireoretinal surgery and silicon oil tamponade. Ultrasound biomicroscopy was performed on the day before silicone oil removal, intraocular silicone oil distribution and anatomic relationship were observed. Duration of silicone oil tamponade ranged between 2 and 18 months. Silicone oil image was clearly seen in all of the silicone oil filled eyes. Its distribution and anatomic relationship to anterior segment structures, ciliary body and peripheral retina. UBM demonstrated the incomplete filling and distribution of silicone oil in the eye, providing useful information in evaluation of silicone oil status in silicone oil filled eye.
