Study Objectives: To determine the relationship of central corneal thickness with the status of diabetic retinopathy and level of HbA1c in diabetic patients. Study Design and Settings: Department of Ophthalmology, Allied Hospital/DHQ Hospital, Faisalabad Pakistan from Jan 2021 to June 2021. Patients and Methods: Out of the patients visiting OPD, 100 patients with clinically diagnosed type 2 DM which satisfied the range of selected standards and offered written informed agreement were involved in the research with the use of simple random sampling. Snellen’s visual acuity chart for distance vision and Jaeger’s chart for near vision were used to determine the best-corrected visual acuity. Wet Refraction and axial length was measured using A-scan. Goldmann applanation tonometry was used to measure the intraocular pressure. Results of the Study: In this research sixty two percent of the patients were men and thirty eight percent patients were women. Total 84 patients had type 2 DM of duration 5-10 years, and the remaining 16 patients had diabetes for over 10 years. Total 35 patients had HbA1c between 4-5.6%, 31 patients had HbA1c between 5.7- 6.5% and 34 patients had HbA1c ≥ 6.5%. From 100 patients with Diabetes Mellitus Type 2, 21 patients had no diabetic retinopathy, 28 patients had very minor and minor NPDR, 25 patients had average NPDR, 19 patients had critical and very acute NPDR and 7 patients had PDR. The mean HbA1c in patients with no diabetic retinopathy was 5.05%. The mean HbA1c in patients having minor and very little NPDR remained 5.64%. The mean HbA1c in patients with moderate NPDR was 6.36%. The mean HbA1c in patients with critical and very acute NPDR was 8.26%. The mean HbA1c in patients with severe PDR was 9.86%. This was a statistically significant survey (P-value = 0.01). Conclusion: This study showed a strong correlation between the central corneal thickness to the severity of diabetic retinopathy and HbA1c levels emphasizes the importance of evaluation of corneal endothelial morphology in the early screening and diagnosis of microvascular complications of DM Keywords: Central Corneal Thickness, Diabetic Retinopathy, HbA1c
Purpose: To determine frequency of post-operative macular edema in diabetic retinopathy patients having received preoperative intravitreal bevacizumab, after phacoemulsification cataract surgery while compared with the controls. Study Design: Quasi experimental trial Place and Duration of Study: Department of ophthalmology eye unit 3, KEMU /Mayo hospital, Lahore from March 2020 to August 2020. Methods: A total of 60 patients were included in the study and randomly divided into two groups. Patients of study group were given 1.25mg bevacizumab injection by IV route two weeks priority to surgery while nothing was administered in the control group. Before one week of surgery ocular examination and OCT were perfumed and it was repeated after every month of performance of surgery. Allocation of patients was even not known to the researcher to avoid biasness. Components of monthly examination were best correct visual acuity, slit lamp examination and central macular thickness quantification with OCT. Standard cataract surgery was performed in all the patients (phacoemulsification and implantation of monofocal intraocular lens (IOL)). Post-operatively, all patients were given standard treatment i.e moxifloxacin-dexamethasone). Follow up of all the patients was made for consecutive three months on monthly basis to assess outcome variables i.e macular edema was observed keeping in view central macular thickness. Results: In patients of study group, 16.66% had developed macular edema while in control group it was observed in 46% patients. While comparing macular edema between side of eye, study group had 02 (13.33%) patients belonging to right eye while 03(20.0%) had left eye. However, in control group it was 08 (53.33%) and 06 (40.0%) for right and left eyes respectively. Group A had 230.23 ± 32.16 µm central macular thickness while it was 274.21 ± 25.34 µm in group B. Conclusion: In macular edema prophylaxis using preoperative intravitreal bevacizumab is efficacious in comparison with the controls in patients with mild-moderate edema.

Objectives: The objective of the study is to assess the retinal redetachment after early and late removal of silicone oil. Place and Duration of Study: Department of ophthalmology eye unit 3, KEMU /Mayo hospital, Lahore from February 2021 to July 2021 . Study: Quasi experimental trial. Patients and Methods: Time of silicone oil removal of first group (29 patients) at 6 weeks and second group (29 patients) at 12 weeks post-operatively. Presence of 360 barrage laser. The two groups were compared as to the condition of the eye at the time of SOR at 1st day 1st week, 1st months.3rd month following SOR. Inclusion Criteria PPV for rhegemantogenous RD with all types of breaks with silicon oil tamponade, both gender 360 barrage laser. Exclusion criteria bands keratopathy grade c PVR, presence of cataract, GRT, only eye Results: The risk of retinal re-detachment was similar in both groups. Conclusion: The danger of re-detachment was not increased by early removal of silicone oil after six weeks, and higher compliance with the removal period was ensured. In patients who are less likely to follow a procedure for delayed removal, it is especially advised..
