About

Anatomical and Visual outcomes of retinal re-surgeries done in silicone oil filled eyes

Full description

• Basic demographic profile including Name, Age, Gender, Place of Residence will be documented.
• structured questionnaire will be used to collect information regarding systemic diseases including Diabetes mellitus and its duration, Hypertension, Dyslipidemia , any cardiovascular diseases, any history of ocular trauma or any other ocular comorbidities.
• Details of the primary retinal surgery including indication, date of surgery, Name of the procedure will be noted
• Details of re surgery including indication (retinal pathology), timing of the re surgery from the primary surgery, preoperative Best Corrected Visual Acuity(BCVA) A using log MAR (Minimum Angle of resolution)) chart at 3 meters, intra ocular pressure using non contact Reichert 7 tonometry will be noted.
• Slit lamp bio-microscopy of the anterior segment using Topcon slit lamp biomicroscope,90 Diopter lens examination and indirect ophthalmoscopy with 20 Diopter lens of the fundus will be done.
• Spectral domain OCT(Optical coherence Tomography) with Zeiss Cirrus HD OCT (High Definition- Optical Coherence tomography) machine will be done for documentation of the status of macula in whichever cases possible.
• Re surgery will be done by a single Senior consultant in all the cases. Alcon Luxor Biomicroscope with Non contact BIOM (binocular indirect ophthalmomicroscope ) viewing system will be used. 2 ports will be made. Top up of Silicone oil will be done whenever needed. Membrane peeling with relaxing retinectomy / drainage retinotomy , haemostasis and endolaser will be done under Silicone oil as required. After the re surgery, the patient will be advised to maintain prone position.
• After the re surgery the BCVA(Best Corrected Visual Acuity), IOP (Intraocular pressure) will be noted on first visit at 15 days, 3rd month and 6th month follow up.
• Fundus examination will be done at all visits. Spectral Domain OCT(Optical coherence Tomography) will be done at all visits to see the status of macula.

STATISTICAL ANALYSIS

• Data entry will be done in Microsoft excel and analysed using the latest SPSS (Statistical Package for the Social Sciences) software.
• Wherever required, descriptive analysis will be done
• Chi square test will be used to find the statistical significance among the qualitative data, •two-tail t test will be used to find statistical significance among the quantitative data pre and post operatively.
• Other statistical tests will be used depending upon the need for post hoc analysis.
