Background:Ocular surface disorders (OSD) are challenging to treat. They can introduce serious morbidity and might even lead to visual loss. In such situations, keratoplasty remains the last option. Amniotic membrane transplantation (AMT) has been shown to be effective in the management of ocular surface pathologies. The aim of the study was to assess the efficacy of AMT for various indications of OSD.Materials and Methods:Experience of AMT in 65 patients with different OSD was evaluated. The aim of AMT was to achieve symptomatic relief, reduced inflammation, recurrence, and corneal haze; improve epithelization, stromal healing and visual acuity; and delay keratoplasty. Fresh amniotic membrane was used in all cases by a single surgeon. Follow-up and observations were done to evaluate success of achieving the goal.Results:Indications for AMT included primary and recurrent pterygium, various types of corneal ulcers (non-healing ulcer, descemetocele, corneal thinning and perforation), spheroidal degenerations, chemical burn and bullous keratopathy. The aim of AMT was different in different etiological indications. Postoperative follow-up was between 6 and 18 months. Success and complication rate were observed. Symptomatic relief (reduced pain and redness) was seen in patients with various corneal ulcers, chemical burn and bullous keratopathy. Improved epithelialization and stromal healing was noted in corneal ulcer cases. In spheroidal degenerations, keratectomy with AMT improved vision. Recurrence of pterygium was low (4.61%); graft failure in the form of graft rejection was seen in only 3.07% cases of acute keratitis. Corneal vascularization (4.61%) was present but not severe enough to hamper vision. Success in gaining intended effect was the most significant result with AMT.Conclusion:AMT in various ocular surface pathologies shows success in achieving the goal of symptomatic relief, improved epithelialization, stromal healing and vision. Reduction in inflammation, corneal haze and recurrence of original disease is achieved with minimum complications.
Purpose:Fornix contracture is an obstacle for fitting a prosthesis in blind or enucleated patients, and may lead to disfigurement and psychological issues. This study evaluates the efficacy of amniotic membrane transplantation (AMT) for fornix reconstruction with the aim of better retention of the ocular prosthesis.Methods:This non-comparative interventional case series includes eighteen blind eyes with fornix deformity in which a cosmetic prosthesis could not be retained. Various causative factors included symblepharon, cyst formation and fornix shortening after enucleation. AMT was performed along with correction of symblepharon, cicatrix release, and excision of the cyst with or without anchoring sutures to reform the fornix.Results:Mean fornix depth pre- and post-operation were 3.72 ± 0.69 and 7.13 ± 0.81 mm, respectively. Fornix deepening was achieved successfully in 15 cases (83.33%). Partial success was achieved in 1 case (5.66%); the remaining two cases (11.11%) were considered as failure despite repeat surgery. Both of these patients suffered from extensive symblepharon formation. Satisfactory results, i.e. formation of a deep fornix to hold the ocular prosthesis, could be achieved in 16 (89.99%) cases. There were no serious complications such as infection or graft rejection.Conclusion:AMT can be a viable option for fornix reconstruction. It has a high success rate in subjects with blind eyes and moderate fornix shortening who are unable to retain an ocular prosthesis.
Careful and intact removal of conjunctival cyst is important to prevent recurrence. Minor modifications in surgical technique according to the size, site and nature of cyst help in intact removal and prevent recurrence.
Purpose:
To evaluate the efficacy of autologous serum in fixing conjunctival autografts of various sizes in different grades and types of pterygium and to determine the largest successfully secured graft size.
Methods:
This prospective interventional study comprised 151 eyes of 151 patients belonging to age group of 21 to 64 years with different grades and types of primary and recurrent pterygium that underwent excision with inferior conjunctivo - limbal autograft secured with autologous serum. The autografts were measured with calipers and were grouped by size into three categories: Group A, small (5 × 5 mm); Group B, medium (5–7 × 5 mm); and Group C, large (>7 × 5 mm). The adhesive fixation power of autologous serum for the various conjunctival autograft sizes was determined for each group using the following criteria: graft stability, cosmetic appearance and complications in the immediate ( first week) and two-months postoperative follow-up visits. Descriptive statistical analysis was used to calculate the percentage frequency of the variables.
Results:
The groups A, B, and C included 48%, 22%, and 30% of the autografts, respectively. Overall, 93.34% of the grafts were stable with good cosmetic appearance. However, subconjunctival hemorrhage (36%), graft edema (36%) and graft retraction (13.5%) were the most common complications. The largest successfully fixed graft was 14 × 5 mm in size.
Conclusion:
Autologous serum is efficient in securing conjunctival autografts of various sizes with minimal complications and satisfactory results, including good cosmesis.
PURPOSEThe aim of this study was to assess bleb function using Wuerzburg bleb classification score (WBCS) for bleb morphology on slit lamp, intraocular pressure (IOP), and gonioscopy.METHODSA total of randomly selected 30 eyes posttrabeculectomy were assessed for bleb function with the trio of bleb morphology, IOP, and gonioscopy. Bleb was assessed using the WBCS of 0–12 on slit lamp, IOP was assessed using applanation tonometry, and visualization of inner ostium and iridectomy were assessed using gonioscopy. Postoperative patients of less than six weeks were excluded from the study.RESULTSThe correlation between WBCS and the duration of trabeculectomy was found to be highly significant (P value = 0.029). The correlation of IOP with WBCS was also found to be strongly positive (P = 0.000). IOP was found to be highly associated with peripheral iridectomy (P = 0.000), internal window (P = 0.001), and bleb characteristics.
