New advances in diabetic retinopathy treatment highlight importance of early detection

Matej Sklenár’s recovery from severe diabetic eye disease underscores recent breakthroughs in treatment and the critical need for early diagnosis and tight blood sugar control to preserve sight.

Matej Sklenár’s case is a stark reminder that diabetic eye disease can advance quietly until sight is already under serious threat. After living with type 1 diabetes since childhood, he began noticing floating spots, streaks and a growing blur in his vision before one eye was almost lost and the other began to deteriorate as well. Doctors at Bory Hospital in Bratislava say he arrived with severe damage in both eyes and little useful sight left on the worse side.

The diagnosis was proliferative diabetic retinopathy, a late-stage complication of diabetes in which poor blood supply to the retina triggers fragile new vessels to form. These vessels can bleed easily, clouding vision and, in advanced cases, pulling on the retina until it tears or detaches. Martin Černák, the ophthalmology chief at the hospital, said the case was especially difficult because the scar tissue had become dense and was already tugging at the retina, making the outcome uncertain.

Sklenár underwent urgent surgery on the eye that had become almost blind, followed by laser treatment and a period in which silicone oil was used to help stabilise the retina while it healed. Over several months, that oil was later removed and treatment continued with further laser and injection therapy. Černák said the combination of surgery, follow-up care and tighter diabetes management helped restore sight to the point where Sklenár now has full vision in one eye and more than 80% vision in the other.

His recovery also reflects a wider shift in diabetic retinopathy care. A five-year study published in JAMA Ophthalmology found that both panretinal photocoagulation, a form of laser treatment, and ranibizumab injections were effective for proliferative diabetic retinopathy, with the injection group showing stronger long-term visual acuity results. Other medical reporting and case stories, including accounts from Cleveland Clinic and Scientific American, have pointed to the same theme: early detection and rapid intervention can preserve vision, while delays make treatment far harder.

Černák said Sklenár’s diabetes control had been poor when he first presented, but improved markedly once he began using a glucose sensor and insulin pump and followed specialist advice more closely. That matters because prolonged high blood sugar damages the retina’s tiny vessels and sharply raises the risk of sight-threatening disease. The doctor said that even a small rise in glycated haemoglobin can greatly increase the chance of advanced retinopathy, underlining why regular eye checks and better diabetes control are essential long before symptoms appear.
