Retinal lesions refer to benign or malignant growths in the retina. Some types are considered very rare. Those that are slightly more common (such as naevi) are non-cancerous or benign. Rare types include retinal astrocytoma (characterised by yellow-white mass that can later become calcified), retinal capillary haemangioma (rare but sight-threatening), retinal cavernous haemangioma (an autosomal dominant inherited condition), and retinal racemose haemangioma (a rare condition characterised by dilated, tortuous fundal vessels).
Retinal lesions are managed with cryotherapy or brachytherapy, photocoagulation, radiotherapy, or surgical excision. Such treatment methods are offered by many ophthalmologists (eye specialists) and eye centres in Southeast Asian countries such as Singapore, Thailand, and Malaysia. One of them is the Singapore National Eye Centre (SNEC), a Joint Commission International (JCI)-accredited specialist medical centre for eye care. It caters to both local and international patients and performs about 14,000 major eye surgeries and 13,000 laser procedures every year. It offers comprehensive eye care and has a dedicated vitreoretinal service. It is an international referral centre for complex cases and a training centre for ophthalmic education around the world. As a JCI-accredited medical facility, patients can expect to receive the services of highly qualified ophthalmologists who use sophisticated technology and world-class medical facilities; the same ones found in Western countries such as the United States and United Kingdom.
Thailand and Malaysia also have a long list of JCI-accredited hospitals with dedicated ophthalmology departments as well as privately own specialty eye clinics that offer comprehensive treatment for retinal lesions. Most of them are also equipped with advanced technology and use advanced methods and breakthrough techniques. Despite these, medical tourists in Southeast Asia get to enjoy significant cost-savings as the cost of comprehensive eye care in the region is up to 75% less than in Western countries.
