a) You may undergo special examinations such as :
Slit Lamp Examination
Pre-employment Check up
Ocular A Scan ( IOL Power ) biometry
Ocular B Scan
Field testing
Fundus Floriscien Angiogram
Optical Coherence Tomography
Corneal Topography
Visual Evoked Potential (VEP)
b) Paediatric patient evaluation :
Paediatric patients will be examined in the OPD by direct examination or after administration of an oral sedative. If the child is not co-operative then examination under general anesthesia (EUA) will be carried out by appointment at a future date.
c) Refractive Error Examination :
Patients with refractive errors, or suspected of having refractive errors, should under go a comprehensive eye examination to establish the condition's present status.
d) Contact Lens Fitting :
People interested in using contact lenses, will, after a preliminary examination, receive guidance about contact lens care and fitting instructions. Existing contact lens users can obtain new contact lenses and receive advice regarding problems related to contact lens use.
e) Low Vision and Visual Rehabilitation :
Patients with low vision that cannot be improved by routine optical aids can be helped by special optical aids and should contact the Vision Aid charitable organization, a specialised low vision aid center.
f) Cataract :
Cataracts are usually caused by the deterioration of the normal structure within the lens of the eye resulting in clouding of the eye's crystalline lens. This is a normal and common part of the aging process. Other causes include injuries
g) Laser Treatment For Correction of Glasses ( LASIK) :
People interested in laser treatment for eye correction must under go a preliminary examination to check their suitability for this procedure.
h) Corneal Diseases and Corneal Transplantation :
Patients with corneal diseases such as corneal ulcer, corneal dystrophies and degenerative conditions will be examined by the Cornea Department which will conduct the necessary tests and advise the patient. Patients requiring a corneal transplant will be registered and called for surgery when donor corneal tissue is available.
i) Glaucoma Screening and Testing :
After preliminary testing special tests such as, Gonioscopy, Field Testing, Measurement of Corneal Thickness (Pachymetry), and Retinal Nerve fibre layer analysis (RNFL) by optical coherence tomography (OCT) will be carried out as required. If laser treatment is recommended for Glaucoma you will be given a specific date and time for surgery on an out patient basis. When surgery is required you must under go a pre-operative physical evaluation and then a surgery will date will be given. Surgery is done on an out patient basis.
j) Diabetic Eye Examination :
. All diabetic patients needs eye examination to rule out diabetic retinopathy. After an initial examination if there is no diabetic retinopathy, you will be asked to come for a further check up after one year. This does not require further special tests.
. In the presence of diabetic retinopathy patients need to under go further tests such as Fundus Florisciene Angiography (FFA). OCT or B Scan. FFA patients will be given an injection in the arm and serial photos will be taken of the eye to check for the leakage of dye from new vessels.
. If the patient requires laser treatment because of the development of new leaking vessels this will be done in 1 to 3 sittings depending on the severity in each eye. Not more than one sitting will be done on each eye per day.
. Patients need to be checked at 6 weeks to 12 weeks after surgery.
k) Retinal & Vitreous Examination :
. If the patients requires retinal examination, for example in cases of blocked blood vessels, age related macular degeneration, high myopia, cataract extraction, detailed indirect ophthalmoscopy or with contact lens problems, examination will be done by a Retina Specialist after complete dilatation of the pupil. A "B scan" or FFA or OCT. may be required.
. If surgery is required then after a preliminary physical examination a appointment for surgery will be made.
l) Uveitis :
Uvitis patients - necessary systemic investigations will be carried out and the required treatment started.
m) Neurophthalmology :
Optic nerve related diseases will be examined by a posterior segment specialist and special tests such as VEP, Fields, and CT/MRI brain scan will be made, if required. The necessary treatment will be advised.
n) Oculoplasty :
People with eyelid problems and other related diseases will, after preliminary examination, be examined by an oculoplaty specialist appropriate tests and surgery will be advised.
o) Squint Check Up :
Patients suspecting the presence of squint can have a squint check up. After a preliminary examination the following test may be carried out.
. Refraction with the use of Cycloplegic (Atropine, Homatopine or Cyclopentolate), for refraction under Atropine, the ointment must applied for three day prior to the examination. Cyclopentolate and Homatropine refraction can be done same day after frequent installation for about an hour.
. Patch Test: Sometimes, to know the amount of squint, one eye will be patched for a period before assessing the amount of squint.
. Amblyopia Treatment : To improve vision in the lazy eye, the better eye is obscured by a patch to encourage the patient to see with the lazy eye. Either a rubber occluder or plasters will be used to close the better eye.
Squint Surgery : Once the doctor advises surgery the patient must have a pre-operative general examination by general a physician or paediatrician to assess fitness of . surgery. Surgery dates depend on the availability of the surgeon. Patients can arrive at the hospital in the morning with an empty stomach and after surgery can stay in hospital until evening. Alternatively he can go home and attend for an examination in evening, or next day, depending on the doctor's requirements.
