Diagnosis of Detached Retina
Diagnosis of detached retina relies on a detailed eye examination by an optometrist or ophthalmologist. When someone presents with symptoms of a detached retina, swift and accurate diagnosis is critical to prevent irreversible vision loss. The evaluation includes a combination of clinical observation, imaging tests, and assessment of visual function.
Initial Clinical Evaluation
The doctor will ask about the onset and nature of symptoms, such as floaters, flashes, or shadowed vision
The eye care specialist takes a thorough medical history, including any previous eye surgeries, trauma, or conditions like diabetes or high myopia
Visual Acuity Testing
Measures how clearly a person can see at various distances
The specialist checks whether central or peripheral vision is affected
Establishes a baseline for monitoring changes before and after treatment
Dilated Fundus Examination
Special eye drops dilate the pupils to allow a clear view of the retina
Using a slit-lamp microscope with a bright light and lens, the doctor can examine the entire retina
Signs of retinal tears, detachment, or bleeding are carefully assessed
Indirect Ophthalmoscopy
A head-mounted light and lens are used to view the peripheral retina in detail
This technique provides a wide field of vision to detect small or hidden retinal breaks
Imaging Tests
Optical Coherence Tomography (OCT):
Produces cross-sectional images of the retina
Identifies fluid accumulation, retinal layers, and subtle detachment
Ultrasound (B-scan):
Used when the view of the retina is obscured by bleeding (vitreous haemorrhage)
Detects full or partial detachment and measures the extent of separation
Fundus Photography:
Captures detailed images for documentation and comparison over time
Differential Diagnosis
The following conditions may mimic or accompany retinal detachment:
Posterior vitreous detachment (PVD)
Retinal vein occlusion
Macular degeneration
Ocular tumours
Urgency of Diagnosis of Detached Retina
A suspected detached retina is a medical emergency
The faster the diagnosis is made, the better the prognosis for preserving vision
In conclusion, diagnosis of detached retina depends on clinical skill and advanced imaging tools. Prompt detection allows for timely surgical intervention and maximises the chances of vision recovery.
