Comprehensive practice of ophthalmology covers a wide variety of pathology and complex nature of the problem. Retina specialist in Dubai is recognised by his ability to diagnose the issue, suggest treatment and perform in-depth clinical trials on the patient. Listed below are common indications and their diagnoses managed best by a retinal expert.
Retinal tear or Rhegmatogenous detachment
Optical anomalies such as highly myopic eyes with matrix deterioration, irregular setting of acute posterior vitreous detachment or trauma leads to retinal tears. In this situation, liquefied vitreous is exposed to the sub-retinal space that further leads to Rhegmatogenous retinal detachment.
If a retinal tear or break is imminent based on medicalhistory of photopsias/floaters or detailed peripheral exam performed with scleral depression discloses one or more breaks, documenting or marking the location is important.
Laser retinopexy is usually referred depending on symptoms and symmetry of the break. If diagnosis ofRhegmatogenous is positive, a retina specialist in Dubai is likely to schedule operative procedure.
Intraocular foreign body
Symptoms of intraocular foreign body must be carefully evaluated in patients who previously sustained penetrating globe trauma. There’re several models used to assess posterior segment intraocular foreign body also termed as B-Scan ultrasound, lateral and frontal skull plain films and non-contrast boosted orbital CT scan.
Foreign bodies can be organic, glass or metallic in nature and if intraocular foreign body is suspected, urgent removal is referred by your imminent retinal specialist. Pars-plana vitrectomy allow careful removal of the foreign body assisted through forceps extraction or rare earth magnet but that depends on whether or not the material is ferromagnetic.
Post-traumatic, post-operative or endogenous infectious endophthalmitis
Urgent referral to a retina specialist in Dubai is crucial in case of positive diagnosis of endophthalmitis. This is done on the basis of intense intraocular inflammation post-intraocular surgery that can be glaucoma filtration or cataract extraction, sepsis/endocarditis (penetrating globe trauma). A patient is likely to undergo limited vitreous biopsy (needle tap) or maybe intraviteral injections (antibiotic injections) if antifungal agents are detected.
High-risk multiple diabetic retinopathy
Diabetic patients suffering from high-risk proliferative diabetic retinopathy (PDR) may result in severe visual loss. High-risk PDR can be defined as mild to moderate and severe disc neovascularisation with or without vitreous hemorrhage.
Referral of retina specialist in Dubai for careful evaluation and administration of anterior and posterior sector neovascularisation is crucial to sidestep development of retinal detachment or proliferative vitreoretinopathy.
Significant or Refractory diabetic macular edema
Clinically Significant Diabetic Macular Edema (CSDME) or suspected diabetic macular edema if diagnosed is corrected through focal laser treatment. Persistent diabetic macular edema even after initial laser photocoagulation is then taken care with modified grid laser treatment, intraviteral triamcinolone injections or a combination of both. For cases of CSDME associated with posterior hyaloids traction, a pars-plana vitrectomy with membrane peel may be indicated.
Given above are a few cases in which immediate consultancy of a retina specialist in Dubai is recommended. Even for minor optical discrepancies, seek advice of a specialist rather than ignoring the symptom else it may lead to a greater anomaly or worse, blindness!
