3M.D., Sisli Etfal Training and Research Hospital, Eye Clinic, Istanbul/TURKEY Purpose: Evaluation of the clinical characteristics and their effect on prognosis of glaucoma cases which developed following vitrectomy or became uncontrollable by medical therapy and needed surgical procedure is aimed.
Materials and Methods: Initial and last visual acuity (VA), intraocular pressure (IOP), additional medical treatment or surgical procedures and latest clinical findings were evaluated in the patients.
Results: Eight eyes of 8 patients were involved in this study. Mean patient age was 49.5±17.9 years. Primary diagnosis included retinal detachment with retinal hole/giant retinal tear, vitreous hemorrhage due to diabetic retinopathy and epiretinal membrane formation. Intraocular tamponades used after vitrectomy included silicone oil in 5 eyes, SF6 in 2 eyes and C3F8 in one eye. Glaucoma surgeries included non-penetrating deep sclerectomy(NPDS) in 3 eyes, trabeculectomy in 4 eyes (with 5-fluorouracil (5FU) in 3 eyes), trabeculectomy with 5FU and phacoemulsification+intraocular lens implantation in one eye and trabeculectomy in one eye following NPDS. Mean preoperative IOP was 29.83±7.80 mmHg in 6 eyes which underwent trabeculectomy. Mean IOP was 22.5±4.80 mmHg (n=6) at postoperative 1st month and 20.6±5.41 mmHg at last visit. Mean follow-up time was 13±8.6 months. Seven out of 8 patients needed antiglaucomatous medical therapy. Median initial VA was seeing hand movements and last median VA was 15/100. Anatomical success was achieved in all but one.
Conclusion: In this case series, glaucoma surgery was found ineffective, and early postoperative antiglaucomatous treatment was needed. Regular and continuous follow-up of these patients is needed.
